> because productivity gains must benefit the lower classes to see a multiplier in the economy
by this logic, the invention of mechanized farm equipment, which displaced farm labor, didnt increase productivity
It made food cheaper.
The benefits largely accrued to the poorest people.
On the contrary, humanity spent nearly its entire existence calorically deficit, and until mechanized farming did we finally see health outcomes improve, height increase, IQ increase, and populations explode.
Productivity gains in the case of mechanized labor got everyone out of subsistence farming and into factories.
AI gets everyone out of every job and into nothing.
